SN74ACT245DWR

Приемопередатчик, семейства 74ACT245, 74ACT, питание 4.5В до 5.5В, SOIC-20.

The SN74ACT245DWR is an octal Bus Transceiver with 3-state outputs. This octal bus transceiver is designed for asynchronous 2-way communication between data buses. The control-function implementation minimizes external timing requirements. When the output-enable (OE)\ is low, the device passes non-inverted data from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR) input. A high on (OE)\ disables the device so that the buses are effectively isolated. To ensure the high-impedance state during power up or power down, (OE)\ should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.

• Inputs accept voltages to 5.5V
• 8ns at 5V Propagation delay (tpd)
